[英]How can I define express middleware for all routes
I am trying to define one global middleware which will work for all routes of my app. 我正在尝试定义一种全局中间件,该中间件将适用于我的应用程序的所有路由。 I tried some ways but still got some issues.
我尝试了一些方法,但仍然遇到一些问题。
var _gMDLW = function (req, res, next) {
if(req.route) console.log('Called route ', req.route.path);
next();
}
// Working fine and result on _gMDLW is /route1
app.get('/route1', _gMDLW, function (req, res, next) { return res.sendStatus(200); })
var globalRouter = new express.Router()
// Working fine and result on _gMDLW is /view
globalRouter.route('/view')
.get(_gMDLW, function (req, res, next) { return res.sendStatus(200);})
app.use(globalRouter);
But problem is here 但是问题在这里
// Error in _gMDLW and getting /list instead of /items/list
var itemRouter = new express.Router()
itemRouter.route('/list')
.get(_gMDLW, function (req, res, next) { return res.sendStatus(200);})
app.use('/items', itemRouter)
Second Question is is there any way to define/add _gMDLW
inside app
instead of adding in each route something like app.use(_gMDLW)
? 第二个问题是,有什么方法可以在
app
内部定义/添加_gMDLW
,而不是在每个路由中添加诸如app.use(_gMDLW)
类的东西吗?
Thank you 谢谢
You can use
app.all()
to resolve this issue您可以使用
app.all()
解决此问题
app.all('*', _gMDLW);
function _gMDLW(req, res, next) {
if (req.path == '/') return next();// redirect to homepage for guest
next();//authenticated user
}
You can modify it as your requirement 您可以根据需要进行修改
